Functions

func Copy

func Copy[T1 comparable, T2 any](m map[T1]T2) map[T1]T2

Copy returns a shallow copy of the given map.

func Filter

func Filter[T1 comparable, T2 any](m map[T1]T2, f func(T2) bool) map[T1]T2

Filter returns a shallow copy of the given map with items that satisfy the predicate f.

func Keys
